It's not a black edition CPU, so you can't OC using multipliers; and
the 965 will be faster in most gaming applications.

Edit #1: I think you're better off going micro-ATX with the 965BE. I mean, downsizing is the whole point for you, right?

Edit #2: Oh, and one more thing to check out: If you remove the hard drive trays in order to install a long video card, will you be able to install multiple drives? Keep in mind you'll need a secondary drive other than your SSD.

Edit #3: I just answered my own question. You're able to move the HDD tray up above where the video card goes (as per the picture)
